I wonder what will be truly knowable about CTE.

Is there real science that will someday say what level of violence/impact is unlikely to cause CTE?

Is there at least going to be a good study linking number of concussions to CTE?

The suspect the answers to even these simple questions are very, very far away, if they are coming at all.

Conscience is going to be our main guide until then.
